BOREAS Black Spruce Xylem Flux Measurements from 1994

120 days of in situ xylem flux density measurements for five black spruce trees, collected during the 1994 growing season. The BOREAS RSS-17 team gathered this data in 30-minute intervals to study water uptake variability. This dataset supports research linking radar imagery to environmental and phenological states.

Use Cases

• Calibrating radar imagery models for forest water status using in-situ xylem flow data.
• Analyzing diurnal and seasonal patterns of tree water uptake in a boreal black spruce stand.
• Studying spatial variability in water use among individual trees within a single forest site.
• Investigating the relationship between xylem flux and environmental drivers over a full growing season.

Strengths

• Provides high-temporal-resolution data with measurements taken every 30 minutes.
• Covers a full 120-day growing season from May to September 1994.
• Data collection is part of the authoritative BOREAS project led by NASA.

Limitations

• Specific column names and the total row count are not documented in any source.
• Sources conflict on the last updated date: one lists 2026-03-13, another lists 1994-09-28.
